Zucan,

I can only wish that I could claim credit for the genus of progressive chesses, which encompasses at least half a dozen or so different game types. The truth is that the basic idea has been with us for at least a few decades.

I presume you played the Scottish version, which is usually the term given to basic progressive. English Progressive was invented around 1982 by an Englishman (no surprise there), who quite correctly wanted to improve on the uncontrolled kamikaze play inherent in the other progressive types. Oddly, no one seems to know the identity of this person, but his creativity spawned a zeal in me unmatched by all other game types!

I played ENPR in an Italian organization until around 2000, when it dissolved; but they used to sponsor tournaments in a wide variety of chess variants. Their chief game was Italian Progressive Chess, which differs only from Scottish in that you have to utilize your full turn or you lose.
